A look at how the big names performed in the opening round of the 2021 U.S. Open at Torrey Pines South Golf Course.

Brooks Koepka, the four-time major winner, and two-time U.S. Open champion, has finished in the top 10 in 14 of his 28 major championship starts. He opened with a 69 and was T5 on 2 under.

Home favorite Xander Schauffele was tied with Koepka after a four-birdie 69.

Pre-tournament betting favorite Jon Rahm was also at 69 alongside reigning Masters winner Hideki Matsuyama.

World No. 1 Dustin Johnson, who’s been in about a five-month slump, shot 71 and was T25 on even-par.

Justin Thomas, the world No. 2 – who’s also been in something of a slump, opened with a 2-over 73.

Rory McIlroy shot 70 and was T11, alongside Patrick Cantlay, Adam Scott.

Patrick Reed, who won the Farmers Insurance Open on the South Course earlier this year, shot 1-over 72 and sits T41.

Bryson DeChambeau opened defense of his 2020 title with a 2-over-par 73, highlighted by two closing birdies on 14 and 18.

Reigning PGA champion Phil Mickelson, who needs a U.S. Open title to complete the career Grand Slam, struggled to a 75. The 51-year old has six runner-up finishes in the U.S. Open.

The 2020 PGA Champion fared no better than the 2021 winner: Collin Morikawa also signed for a 75 and sits eight shots off the lead.

Gary Woodland, the 2019 U.S. Open champion shot 74, while four other former winners were even worse: Martin Kaymer (2014) and Jordan Spieth (2015) matched 6-over 77s; Justin Rose (2013) carded 78, and Webb Simpson (2012) shot 79 – his worst-ever U.S. Open round.

Francesco Molinari, the 2018 Open Champion, and bother Edoardo Molinari, the 2005 U.S. Amateur champion, shot 68 and 70, respectively, putting them in position to become the first brothers to make the cut in the same U.S. Open since Joe and Masashi “Jumbo” Ozaki in 1993 at Baltusrol.
